This inventionrelat-es to cementing nia-' chines'an'd'more particularly tothe type employed inthe manufacturev of boots and shoes for applying cement uniformly to marginal portions of leather or other material such for instance as Vamps. A principal ob ject of the invention is to provide an improved means whereby the material piece such as'a shoe vamp is protected andguard ed fromdaubing or's'mearing with cement on any portion ofv the surface thereof except the edge to be cemented. To this end one feature of the invention consistsin the provision of improved means for clearing the work from the applying roll and fromthe adjacent table surfaceas soon as it passes the-cement ing point while another feature consists in improved means for cleaning eifectively the backing roll which co-operates with theapplying roll of any cementthat it may pick up in. its operating function: I A still further feature consists in an improved construction of cement gauge or-scraperthat is combined with andborne by an adjustable work table. A further feature relates to an improved con struction of work gauge and guide adapted to be located at theend of an extended horn or neck in which the-applying roll is mount- 6Cl,' 2II1d operative to guide and direct a work piece being operated onsuch as a closed vamp away from the-machine as fast as it is cemented. thus further preventing daubing or smearing. Another object is to provide means associated with the carrier. ofthe backing. roll adapted to be set optionally for holding said roll: normallypressed' toward the applying roll or awaytherefrom.' The foregoing. andothe'r objects, and advantages of the invention willimoreifully'appean from bodying the invention the following detailed description, and the distinctive featuresof novelty will be pointed out in the appended claims.

Referring to the drawings: Fig; l is aside elevation of a machine em- Fig; '2' is 'a' vertical lengthwise section thereof looking from the side opposite to that of Fig; 1; i i

10 indicates the machine frame, theintesectional detail on rior of which is hollow to constitute a ce- 1 ment reservoirll, thetop of whichis noradjacent its opposite-ends arefprovided' spacedapart hearings 15 in which is joun naled a shaft 16 havingfixed on a projectingl rear end thereof driving pulleys 17, one

of'these beingfast. to serve as a driving pal-- ley and the other. being loose as usual. The

forward end of the shaft lfiprojects into .an

elongated. horn orneck18 secured to the top of the'machine frame at'the' front endthereof either by threading ther'einto with a securing-screw 19 asshown or otherwise as may be preferred} The extremity. ofthe shaft- 16 within the horn 18has fixed thereto a cement applying roll 20 suitably grooved peripherally and'l engthwise thereof as usual,

this roll thus occupying the outer end perti'on-of the horn: 18 and projecting up.

through the top thereof to present an exposed cement applying edge. -Th1s cement applyingedge projects through a work table 21 slidably fitted to transverse undercut ways 22in a flattened top surface on the outer portion of 'the" 1iorn,- the outer ione'of;

end cap 24 forming a detachable end closure for the born 18. in accordance with our invention the table 21 extends at one side of the horn with a downturned projection 21 to which is swiveled as seen at 25 an adj usting screw 26 with a knurledoperating head 26 which is threaded into the metal of the horn. in accordance with our invention the work table 21 itself is made to constitute a cement scraper and gauge, for this purpose having a formed edge 27 adapted to be ad 1 gauge spaced away from and below the table the cement can'crawl over the gauge and flow again on to the roll more or less thereby losing control of the cement. It is to be noted that the provision of the. screw 26 swiveled to the table permits the use of an adjusting screw worming parallel to the table face and thus to best advantage as will be understood. For supplying cement constantly to the horn 18 suitable means shown as a screw conveyer 28 is provided working in a tubular way 29 in the bottom of the reservoir, this screw having its shank journaled and swiveled at 30 in the machine base and having drive connection through a gear train 31 from the prime drive shaft 16. The operation of this screw delivers the cement to a vertical passageway 32 closed off at the front of the machine by means of a trans verse barrier 83, the upper part of this barrier being constituted by gate 33 adapted to be adjustably clamped by means of a bolt roll, such adjustment being desirable on account of varying degrees of thickness and viscosity in different Kinds of cement. For co-operation with the applying roll 20 a backingand presser roll or disc 36 is provided, this roll being positively driven in unison with the applyingroll and thus cooperative therewith also as a feed roll for advancing the material. The backing roll 36 .isfixed at the outer extremity of a shaft 37 journaled in bearings 38, 39 at the inner and outer extremities respectively of an .overhanging'arm 40 pivoted at 4.1 to the rear of the machine frame in bearinglu'ackets 4-2 that may be formeclon and extend up fro'm'the cover 12. The arm' 40 is adjust ably limited as to its downwardmovement by an adjustable screw bolt e3 threaded therethrough and adapted to impingeon the machine top to thus determine the clownward movement of the roll 36while a stop set into a lug at the rear of the arm en- 1 gages a fixed lug on the machine frame to limit the upward movement thereof. lhe shaft 37 is driven constantly in unison with the shaft 16 by a pinion l5 meshing with the gear 31 on the shaft 16. For operating the swinging arm =l0,it is engaged by the outer extremity of an arm' 46 loosely mounted on the pivot pin 41 andhaving rigid therewith another arm 4;? which may be connected to a suitabletreadle (not shown). F or tensioning the arm 40 a leaf spring 4-8 is provided this spring being anchored. at one end to disc 4:9 clamped for angular adjustment on an outer extension of the pin 41 by means of clamp screws 50. The free end of this spring engages a p n 51 carried by the arm M. The

purpose of this construction is to provide for setting the spring so as to tension the arm 40 either for upward or downward swinging accordingto the kind of work in hand. Thus for operating on closed vamps the arm should be tensioned to swing non mally upward while for-open Vamps and with continuous feedwork the arm should be tensioned to swing downwardly. The. change from one setting to the other by the present construction is attained by'loosening the set screws 50 and turning the disc 49 on the shaftll either to the left as seen in Fig. l. for tensioning the arm upward or to the right for tensioning the same downward. For clearing and cleaning the backing .roll 36 of any cement that may be gathered up thereby, a scraper or clearer plate 51' is pro .vided fixed at the lower side of a hollow 'jecting from the forward end of the arm 40 to which it is clamped bya screw 55. Ihe arm 53 is mounted to turn. on the pin 5.4 and it is tensioned by a coil spring 56 mounted on the pin 54 one end of said spring engaging the arm 53 while its othe' end is an chored to a collar5'i' angularly adjustable on the pin 54 so that the tensioning of the arm 53 may be varied. The hollow passage 52 in the head 552 communicates with a flex-- ible return tube 58. one end'of which is car-- ried the head 52. and the other end of which empties down into the reservoir through the cover 12. This dischargeend of said tube as seen at 59 is above and adjacent to the shaft 16 wlierefron'i'it results that the viscous cement will be wound on to the shaft 16 and thus drawn out through the tube 59 in this way facilitating the return movement of the cement. It is desirable that the cement onits return course'as well as the body of cementin the reservoir be kept from contact with the air and as far as possible and, for this purpose as well as to facilitate the 1 return cement movement we -provide an ad i 1-; 446MB justabl'e gate formed as anarc'uate plate *60 shallow pocket is formed in which a qua-ntity of cement as gathered by theroll"36an'd cleared as described will ttCCUl'DlllittGlIl operation,' and the adjustment'of the gate'GO may be made such that'ior any particular kind of cement there will be just-enough accumulation to seal the opening into thep'assage 52* without an excess accumulation sufficient to overflo\v,'thus keepingthe return passage sealed and makingthe cement return more uniform and effective! v The clearer or scraperplate 51 which is hel'd in operative relation to the 'roll '36 by the spring 56 keeps the roll '36 substantially cleaned and cleared of cement but to further clean this roll so'that it-will neeeven in the slightest degree" soil" the incoming material, we'preterably provide a secondarywiper or cleaner member formed as a box or holder 6E2 in which textile waste o'r'like cleaning material may be carried, this box being held pressed forward so that its wiping contents engage the roll, by aspring plate 63,-which serves as its mounting and is itselt adjustably clamped as seen at64' to the forward end of the ar'mAO. This wiper boxfwhicjh-is located just below the scrape-r plate "51" is thus adapted to complete cleaning of the roll 36 just before it engages the inco'in ing material.

In accordance with our invention the horn as seen at 67 to the side of the horn and ex tending transversely of the axis thereof inward and also bowed inso that its extremity engages in an intermediate groove of the applying roll as seen at 68. a The purpose of the wire 65 is to break and remove the cement tending to cling between the two rolls while the transverse wire 66 prevents the material. piece being doubled up by the movement of the wheels or becoming clogged between the table edge and the roll i. e., this cross wire '66 is in the nature of a work clearer and its point extends down into the roll so as to prevent the cement from flowing therealong. We also preferably provide a flange piece 69 at the outer extremity of the horn presenting a gradually inclined edge 69 to the material piece in'the direction of feed; the purpose of this being to guard the cemented edge and keep it from coming prematurely into contact with any foreign matter which would adhere thereto. When the machine islto be use'd foroperating on closed vanfldswe provide a yspeci'al form of a work gauge indicated'atO this b'eing adj ustably c lampedito theenthofthe=hornby a screw slot71 and having'jan inclined work gauging and-guiding edge 72extend1ng over the applying ro'il-anda gauge wall? 3 ali'ned with the outer "edge of the" applying roll.
